Adamsberg travels to London, where a routine conference draws him into a disturbing investigation.
Commissaire Adamsberg leaves Paris for a three-day conference in London. With him are a young sergeant, Estalère, and Commandant Danglard, who is terrified at the idea of travelling beneath the Channel. It is the break they all need, until a macabre and brutal case comes to the attention of their colleague Radstock from New Scotland Yard.
Just outside the baroque and romantic old Highgate cemetery a pile of shoes is found. Not so strange in itself, but the shoes contain severed feet. As Scotland Yard's investigation begins, Adamsberg and his colleagues return home and are confronted with a massacre in a suburban home. Adamsberg and Danglard are drawn in to a trail of vampires and vampire-hunters that leads them all the way to Serbia, a place where the old certainties no longer apply.
